It seems more simple than before.
Instead, please merge patch1/2/3 to one patch. and drop the patch4.

But, I think that you better to drop the cleanup patch from this series
because the series[1] touch the exynos-bus.c driver for coupled regulator.
[1] https://www.spinics.net/lists/arm-kernel/msg741971.html
I recommend that you send the cleanup patch with my comment
either after reviewing the Kamil's patch[1] or rebase this series base
on patch[1].
